If you're on the hunt for a transfer case that won't let you down, you might want to check out what Zumbrota Drivetrain has to offer. They’ve been in the remanufactured transfer case game for a while now, and they know their stuff. As vehicles evolve and get more complicated, Zumbrota has stepped up their game too, refining their manufacturing techniques to keep up. It's this kind of dedication that keeps customers coming back, and honestly, it’s what you want in a part like this.

When you grab one of their remanufactured transfer cases, you’re getting something built with care. They follow strict specs throughout the whole process, which means you can feel good about installing it or even reselling it down the line. It’s all about peace of mind, right?

What Makes These Transfer Cases Stand Out:

• They don’t just slap these together. Quality inspections happen three times during the remanufacturing journey. That’s right—three times!
• A pre-inspection kicks things off, checking for case cracks and wear. They catch those OEM issues before they become a headache.
• Then, during the reman process, they double-check that all parts meet OEM specs. You want everything to fit and function like it should, and they get that.
• Finally, there’s a post-build inspection to ensure everything meets their strict standards. No cutting corners here.
• Each case is cleaned with a hydro blasting process that brings it back to that OEM finish. Seriously, once you see it, you’ll get what I mean.
• They replace all the seals, bearings, viscous couplers, and other wear components. You won’t have to worry about those common issues cropping up.
• Your transfer case arrives in high-density plastic totes, so it doesn’t get banged up during shipping. A little extra care goes a long way.
• And just to sweeten the deal, these units come with a solid 2-year unlimited mileage warranty. That’s confidence in their work.
